At 12 57, Sabrina cycled from the mall towards the mosque while Jen cycled from the mosque towards the mall. At 13 12, the two cyclists passed each other. 10 minutes later, Sabrina reached mosque but Jen was 1070 m from the mall.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the mosque and the mall in km.
(a)
From 12 57 to 13 12 = 15 min
Combined speed of the two cyclists
= 1070 ÷ (15 - 10)
= 214 m/min
(b)
Distance between the mosque and the mall
= 15 x 214
= 3210 m
1000 m = 1 km
3210 m = 3.21 km
Distance between the mosque and the mall = 3.21 km
Answer(s): (a) 214 m/min; (b) 3.21 km
