At 13 57, Gabby cycled from the school towards the mosque while Usha cycled from the mosque towards the school. At 14 17, the two cyclists passed each other. 15 minutes later, Gabby reached mosque but Usha was 1195 m from the school.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the mosque and the school in km.
(a)
From 13 57 to 14 17 = 20 min
Combined speed of the two cyclists
= 1195 ÷ (20 - 15)
= 239 m/min
(b)
Distance between the mosque and the school
= 20 x 239
= 4780 m
1000 m = 1 km
4780 m = 4.78 km
Distance between the mosque and the school = 4.78 km
Answer(s): (a) 239 m/min; (b) 4.78 km
