Answer:
Distance=Speed×Time
When speed is 40 kmph
Distance traveled by car =40×9
=360 km
When speed is 60 kmph
Time taken to complete the journey =
60
360
=6 hours
First, you have to think of any perfect squares that multiply to 112. The only ones I can think of are 16 and 7. So now you have the square root of 16 * 7. Now you can reduce the 16 because the square root of 16 is 4. So the answer is 4 times the square root of 7.
Answer: The slope of the line is 15 and y-intercept is 12.
Step-by-step explanation: We are given to find the slope and y-intercept of the straight line defined by the points (3, 57) and (5, 87).
We know that
the slope of a line passing through the points (3, 57) and (5, 87) is given by

Since the straight line passes through the point (3, 57), so its equation will be

So, the required equation of the straight line is 
Thus, the slope of the line is 15 and y-intercept is 12.
