Question

Kim and jim went on a 42-mile canoe trip. they have traveled 6 miles per day for three days. if they maintain that rate, how many more days would they need to finish the trip?

Answer 1

Answer:

They need 4 days to finish the trip.

Step-by-step explanation:

Kim and Jim went on a 42-mile canoe trip.

They have traveled 6 miles per day for three days.

Their travelling rate per day = 6 miles.

To cover 42-mile trip at the rate of 6 miles per day they need total = $\frac{42}{6}$ = 7 days

They traveled 3 days now they need to finish the trip = 7 - 3 = 4 days.

They need 4 days to finish the trip.

Answer 2

Their daily rate is $v= \frac{6}{3}=2$ miles per day

Using distance-speed-time formula, we can calculate the time $t= \frac{s}{v} = \frac{42}{2} = 21$days

They need 21-3=18 more days to finish the trip
