Answer:
it is solved at jemrare dot com
Explanation:
This problem can be solved using distance formula;
s=vt
Here we suppose;
Speed of Tourists=v1=4 km/h
speed of bus=v2=60km/h
Total time to be taken by the tourists to reach the camp without bus=t
Time taken by tourists when bus used=t-2h20min=t-140min
let the total distance is ‘x’ but half is travelled without bus and other half by bus!
for first half distance=s1 =x/2
for second half distance=s2=x/2
Using s=vt formula for first half;
