Question

Lucy cycles 8.4km in 18 minutes. Work out her average speed in km/h and explain.

Answer 1

Answer:

The answer to your question is: 28 km / h

Step-by-step explanation:

Data

distance = 8.4 km

time = 18 min

speed = ? km/h

Process

Convert min to hours

                                    60 min ----------------  1 h

                                    18 min   ----------------   x

                                    x = (18 x 1) / 60

                                    x = 0.3 h

                                 speed = 8.4 / 0.3

                                 speed = 28 km / h
