Question

a car travel 120 miles in hours (with a constant speed) . How far will it take to travel 200 miles?

Answer 1

Answer:

one hour 40 min

Step-by-step explanation:

Answer 2

Let the speed of 1st car and 2nd car be u km/h and v km/h.

Respective speed of both cars while they are travelling in same direction = () km/h

Respective speed of both cars while they are travelling in opposite directions i.e., travelling towards each other = () km/h

According to the given information,

Adding both the equations, we obtain

Substituting this value in equation (2), we obtain

v = 40 km/h

Hence, speed of one car = 60 km/h and speed of other car = 40 km/h
