Answer:

The distance travelled is 7.98×10³ miles.

Step-by-step explanation:

Given that the formula to find distance is Distance = Speed×Time. Then you have substitute the values into the formula :

$distance = speed \times time$

Let speed = 5.7×10²,

Let time = 1.4×10¹,

$d = (5.7 \times {10}^{2} ) \times (1.4 \times 10)$

$d = (5.7 \times 1.4) \times ( {10}^{2} \times 10)$

$d = 7.98 \times {10}^{3} miles$
