Answer:
17/8
Step-by-step explanation:
Step 1: Multiply the whole number part (2) by the denominator (8).
2 × 8 = 16
Step 2: Add the product from Step 1 (16) to the numerator (1).
16 + 1 = 17
Step 3: Write that result (17) above the denominator. So,
2 1/8
= 17/8
One crew is doing 1.3 miles daily, the other is doing 1.4 miles daily, so both together are doing 1.3 + 1.4 miles daily, namely 2.7 miles.
now, they are 6.75 miles apart, how many days will it be at a rate of 2.7 miles per day, that 6.75 miles will be done?
days
We use the formula : Displacement = Average Velocity * Time ;
17 = ( v + 8 ) * t ;
1 = ( v - 8 ) * t ;
where v = the velocity of the boat; t is the time from expression " ... in the same amount of the time he rows ....."
Then 17 / 1 = (v + 8) / ( v - 8 ) ;
v + 8 = 17( v - 8 );
v + 8 = 17v - 136 ;
144 = 16v ;
v = 144 / 16;
v = 9 mph ;
18 = 9 * x ;
x = 18 / 9 ;
x = 2 hours ;
The answer is 2 hours ;
Answer:
