Question

A truck can travel 90 miles in the same time that it takes a car to travel 105 miles. If the truck's rate is 5 miles per hour slower than the car's, find the average rate for each.

Answer 1

t: s1=90miles (distance truck travels it t hours)

t: s2=103miles (distance car travels in t hours)

v1=(v2-5)mph (relation btwn speed ot truck, v1 and car, v2)

 

v1=s1/t=90/t 

v2=s2/t=105/t

 

v1t=90
v1t+5t=105

5t=15

t=3

v1=90/3=30mhp (avereage speed of truck)

v2=105/3=35mph ( (avereage speed of car)
