Answer:
Given:1) Speed=42km/hr. 2) Time=5hr
By formula :
Speed=distance/time………(1)
Distance=Speed*time
So,
Distance=42km/hr*5hr=210 km
Therefore,time required when speed is increased by 8 km/hr:
Time =Distance/speed….from(1)
Increased speed=(42+8)km/hr=50km/hr
Time=210/50
Time=4.2hr
Time required when speed is increased by 8km/hr is 4.2 hr.
