A driver of a car moving with a uniform speed of 40m/s observes a truck approaching in the opposite direction with a speed of 20m/s.Calculate the speed of the car relative to that of the truck

Answer 1

60m/s

Step-by-step explanation:

since both are travelling in opposite direction,

relative speed will be the sum of the speed of both the vehicles

= 40m/s + 20m/s

= 60m/s

and we are done!
