Answer:
Step-by-step explanation:
First you need to convert them to one common measurement... I'll use cm for the measurement.
- 1m = 100 cm
- 10 cm = 10 cm
- 50 mm = 0.1 cm
- 1 km = 100000 cm
Using this info to convert gives

Answer:
the cyclists rode at 35 mph
Step-by-step explanation:
Assuming that the cyclists stopped, and accelerated instantaneously at the same speed than before but in opposite direction , then
distance= speed*time
since the cyclists and the train reaches the end of the tunnel at the same time and denoting L as the length of the tunnel :
time = distance covered by cyclists / speed of cyclists = distance covered by train / speed of the train
thus denoting v as the speed of the cyclists :
7/8*L / v = L / 40 mph
v = 7/8 * 40 mph = 35 mph
v= 35 mph
thus the cyclists rode at 35 mph
