1st line gives the information that speed of C is 40m/h and B is 30m/h
Now it says that car overtake bicycle and continued for 15min to reach waiting point.
So in 15 minute car will travel 40*15/60=10 miles
(Concept speed*time=distance)
Now the ques asks how much time bicycle will take to reach waiting point or how much time bicycle will take to cover 10miles. Apply the same S*T=D
We know that B is 30m/h and distance we know 10miles so time is 1/3hr which is 1/3*60=20min

A car and a bicycle are traveling in the same direction along the same route, with the car moving at 40 miles per hour and the bicycle at 30 miles per hour. The car passes the bicycle and then continues for 15 minutes before reaching a waiting point. How long will it take the bicycle to reach the waiting point after the car has passed it?
A. 15 min
B. 20 min
C. 25 min
D. 30 min
E. 35 min
A car and a bicycle traveled in the same direction along the equal route at their constant speed rates of 40 miles per hour and 30 miles per hour, respectively. After 15 minutes the car passed the bicycle, the car reaches a waiting point, how long it takes the bicycle to reach the waiting point?
