<span>time for airplane = 11 am to 1 pm = 2 hr
distance travelled by plane = 2a ------- (speed of plane is a mph)
time for auto = 3 am to 1 pm = 10 hr
distance travelled by plane = 10(a – 200)
2a = 10(a – 200)
8a = 2000
a = 250 mph ----- plane
and 250 – 200 = 50 mph ----- auto </span>

Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
The rule apply for the multiplication and division is :
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The given expression is:
