Tara has ridden her bike .5 miles and rides 10 miles per hour. Felipe has
ridden his bike .25 miles and rides 15
miles per hour. For what number of
hours will-Tara have ridden less miles
than Felipe?

0.5 hours

Step-by-step explanation:

Given that Tara has covered 0.50 miles and  rides with a speed of 10 miles/hour. Felipe has  covered bike 0.25 miles and rides with a speed of 15  miles/hour.

Tara has covered more distance while the speed of Felipe is more than the speed of Tara.

Assuming that in time t hour, Felipe reaches Tara, then Tara left behind as Felipe has faster speed.

So, after t hour, Felipe will be ahead of Tara and Tara will cover lesser miles than Felipe .

As distance = speed x time, so

So, the distance covered by Tara in hour = 10t miles and she already has covered 0.5 miles, so total distance covered by Tara miles.

Similarly, the distance covered by Felipe in hour = 15t miles and he already has covered 0.25 miles, so the total distance covered by Tara miles.

Therefore, at the time then Felipe reached Tara, both have covered the same distance, i.e

hour

Hence, after 0.5 hours Tara will cover lesser miles than Felipe .

step-by-step explanation:

use that smart brain

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
