Question

Mohan is on the swim team. Each day he swims 850 m. How far does he swim in 9 days? Write your answer in kilometres.

Answer 1

Answer:

7.65km

Step-by-step explanation:

Distance Mohan swims each day = 850m

Distance he will swim in 9days = 850m × 9 = 7,650m

Since, 1m = 1/1000km ; 7,650m = 7650/1000 km = 7.65km

Answer 2

If he swims 850 meters ever day for 9 days, multiply 850 $\times$ 9 to find how many meters he swam in those 9 days.

850 $\times$ 9 = 7,650 meters

However, we must write our answer in kilometers.

There are 1,000 meters in a kilometer. To convert meters to kilometers, divide by 1,000.

7,650 ÷ 1,000 = 7.65 kilometers

He swam 7.65 kilometers in 9 days.
