He then drove back on his bike at the speed of 60 km /h.The entire trip took him four hours. how far is Sum it's house from Ravi's house?

Answer 1

s=d/t
d/15+d/60=4hr
distance=48/2=24km

Answer 2

Answer:

48km

Step-by-step explanation:

given

speed = 15km/hr

2nd speed = 60km/hr

time =4hrs

we have to find distance

time = distance/speed

4 = d/15 + d/60

LCM of 15&60 is 60

4= d×4/15×4 + d/60

4= 4d/60+d/60

4= 5d/60

4×60= 5d

240= 5d

240/5 = d

48 =d

therefore total distance is 48 km
