Question

Jack and Charlie cycled from home to park along the same route at 11 km/h and 8 km/h respectively. Jack left home 1 h later than Charlie and arrived at the park 1/2 h earlier than Charlie. How long did Jack take to cycle from home to park?

Answer 1

11t = 8(t + 1) - 0.5

11t = 8t + 8 - 0.5

3t = 7.5

t = 7.5 / 3

t = 2.5

2.5 + 1

3.5 hours

Jack took approximately 3.5 hours to cycle from home to the park.
