At 7 a.m., Flynn left Hotel W in his car and travelled towards Hotel X at 87 km/h. At the same time, Wesley left Hotel W in his car and travelled in the opposite direction towards Hotel Y. When Wesley reached Hotel Y at 9.20 a.m., Flynn was 20 km away from Hotel X.
- What was the distance from Hotel W to Hotel X?
- If the distance between Hotel X and Hotel Y was 440 km, what was Wesley's speed?
(a)
From 7 a.m. to 9.20. am = 2 h 20 min
60 min = 1 h
1 min =
160 h
20 min =
2060 =
13 h
2 h 20 min = 2
13 h
Distance from Hotel W to Hotel X
= 87 x 2
13 + 20
= 87 x
73 + 20
= 203 + 20
= 223 km
(b)
Distance travelled by Wesley
= 440 - 223
= 217 km
Wesley's speed
= 217 ÷ 2
13 = 217 ÷
73 = 217 x
37 = 93 km/h
Answer(s): (a) 223 km; (b) 93 km/h
