Answer:
1.
Given:
distance (d)= 140km
travel time, (t)= 2hrWe know:
speed (v) = d/t = 140/2 = 70km/hr
2.
Given:
distance travelled in 3 hours = 180 km
Therefore,
distance travelled in 1 hr = speed in km/hr = 180km/3hr = 60km/hr
So, in 15 hrs, distance travelled will be -
Distance = speed *time
= 60*15 km
= 900 km.
