Answer 1

Answer:

Estimated time = 490 seconds

Exact time = 463.98 seconds

Step-by-step explanation:

The car traveled 1 mile in 70.3 seconds.

We want to find how long it took to travel 6.6 miles.

We are told to estimate the given values to the nearest whole numbers before solving.

Thus;

1 mile was travelled in 70 seconds

Then; 6.6 miles ≈ 7 miles

Thus, 7 miles is travelled in; 70 × 7/1 = 490 seconds

Estimated time = 490 seconds

Now, exact time will be;

Exact time = 70.3 × 6.6/1

Exact time = 463.98 seconds
