Adistance of 150 km was covered by a motorcyclist traveling at a average speed of 75 km/h by a bus 60 km/h a truck at 50 km/h and a bicyclist at 20 km/h how much time did it require to travel the entire distance

The time required to travel the entire distance is 2.93 hour.

Step-by-step explanation:

Given that,

Distance = 150 km

Speed of motorcyclist = 75 km/h

Speed of  bus =60 km/h

Speed of truck = 50 km/h

Speed of bicyclist = 20 km/h

We need to calculate the average speed

Using formula of average speed

Put the value into the formula

We need to calculate the time

Using formula of speed

Where, D = total distance

t = time

Put the value into the formula

Hence, The time required to travel the entire distance is 2.93 hour.

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
