abdul's average speed is 20 mph in heavy traffic, and his average speed is 50 mph in light traffic. if he was in heavy traffic for 1 hour and light traffic for 2 hours, how far did abdul travel?

choose one of the following answers and provide an explanation:

a. 140 miles
b. 120 miles
c. 30 miles
d. 70 miles

B. 120

Step-by-step explanation:

so his average speed is 20 mph in heavy traffic, and 50 mph in light traffic

in 1 hour of heavy traffic, he would have gone 20 miles because if his average speed is 20 mph (miles per hour) in heavy traffic, then in 1 hour he would have gone 20 miles

20(1) = 20

in 2 hours of light traffic, he would have gone 100 miles because if his average speed is 50 mph (miles per hour) in light traffic, then in 2 he would have gone 100 miles

50(2) = 100

in total, if you add the 20 and 100, you find out how far abdul traveled:

20 + 100 = 120

so in 1 hour of heavy traffic and 2 hours in light traffic, abdul would have traveled 120 miles

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
