You are to drive 300 km to an interview. The interview is at 1115 A.M. You plan to drive at 100 km/h, so you leave at 800 A.M. to allow some extra time.You drive at that speed for the first 100 km, but then construction work forces you to slow to 40 km/h for 40 km.What would be the least speed needed for the rest of the trip to arrive in time for the interview?

Distance and Speed

The speed, distance and time relation forms the basis of study of motion. You will need these concepts in the study of Mechanics. This concept is applicable for students who are studying the following courses –
