Question

David cycles x km in 3 hours. if he maintains the same average speed, how far can he cycle in 12y minutes

Answer 1

Answer:speed=x/3 kmph

Time=12ymins=1/5hr

Distance=s*t=x/15 kmph

Answer 2

Answer:

$Distance \ traveled = \frac{xy}{15} \ km$

Step-by-step explanation:

Distance traveled by David in 3 hr = x km

David's speed = $\frac{x}{3}$ km/hr

12y minutes = $\frac{12y}{60} = \frac{y}{5} hr$

Distance traveled by David in 12y minutes or $\frac{y}{5}hr$ = Speed * Time

                                                                                 = $\frac{x}{3}*\frac{y}{5} = \frac{xy}{15}km$

$Distance \ traveled = \frac{xy}{15} \ km$
