Question

Two​ vehicles, a car and a​ truck, leave an intersection at the same time. The car heads east at an average speed of 70 miles per​ hour, while the truck heads south at an average speed of 60 miles per hour. Find an expression for their distance apart d​ (in miles) at the end of t hours.

Answer 2

Answer:

Let:

distance travelled by car=70*t

distance travelled by truck=60*t

truck travels south while car travels east and hence form a right angled triangle. The distance between them is the length of the hypotenuse of the right angled triangle.

(Truck towards south)

d=√((t*70)^2+(t*60)^2)

= √ (t^2(4900+3600))

d=t* √(4900+3600)

d= t* √8500

d=t*92.19
