Question

Ralph jogs from his home to the stadium at 10km/h. His trip home takes exactly one hour less because he takes a car traveling at 60km/h. How far is it from Ralph's home to the stadium?

Answer 1

Answer:

Step-by-step explanation:

Distance> 60 Km

let time taken for jogging be x

x=distance/10 km per hour    time = distance/speed

distance = x * 10

time taken by car = x-60

x-60 = distance / 60km per hour

distance = (x-60)*60

x*10 = (x-60)*60

x= 72

That means Ralph takes 72min to walk.

So the distance is:

Distance=time x speed

Distance= (72 x 10)/60 = 720 /60

=12 Km

Pls mark mine as the brainliest answer as i took time to solve it.
