Answer:
2203
Step-by-step explanation:
product of 68 and 32
= 32× 68
= 2176
adding 27
=2176 + 27
= 2203
If the speed of the stream is x
Time is given by d/r , where r is the rate and d is the distance;
Rate for upstream = (15-x) mph and that of down stream is (15 +x) mph
The time taken will be the same;
Thus; 2/(15-x) = 4/(15+x)
cross multiplying;
30 +2x = 60 -4x
6x = 30
x =5
Therefore the rate of the river is 5 mph
80 Because the numbers are going up by 10
Answer:
The decimal will move 1 place value to the left. For example 10 to the first power is 10 so 15.3/10 will equal to 1.53.
