If you were travelling at 30 miles per hour how long would it take to travel a distance of 70 miles?

Time=distance/speed

Distance is 70 miles, speed is 30 mph

Time=70/30

As with the speed method of calculation the denominator must fit into 60 minutes.

Time=70/30=2.33

2.33*60=140=2 hr 20 min

.
Complete the Given Series

Which number replace question mark in the series 7, 12, 19, ?, 39.

Which number replace question mark in the series 7, 12, 19, ?, 39.

Clearly, the given sequence follows the pattern:

+5, +7, +9 ... i.e., 7 + 5 = 12, 12 + 7 = 19, ... .

So Missing Number = 19 + 9 = 28.

Hence, the answer is (B)..

What is (999 âˆ’ 99 + 9) Ã· 9?

First work out the value of the expression in the brackets and then divide the result by 9. This gives (999 âˆ’ 99 + 9) Ã· 9 = 909 Ã· 9 = 101. Alternatively, we can first divide each number in the bracket by 9 and then evaluate the resulting expression. This gives (999 âˆ’ 99 + 9) Ã· 9 = (111 âˆ’ 11 + 1) = 101.
