Yuki888 [10]

Answer:

about 3 1/2 hours long

Step-by-step explanation:

70 goes into 240 evenly 3 times, and 70×3 equals 210. that leaves 30 miles remaining. since he is moving at an average rate of 70mph, 3/7 would be the remaining time. to decimal that equals a total of about 3 hours and 25 minutes, which, rounded up, equals 3 and 1 half hours.

Irina-Kira [14]

Answer:

73 feet.

Step-by-step explanation:

Given:

A rope from the top of a pole is anchored to the ground which is 55 ft away from the base of the pole.

The pole is 48 ft tall.

Question asked:

What is the length of the rope?

Solution:

Here we found that a right angle triangle is formed in which base and height is given <u>as shown in the figure, </u>we have to find the longest side of the triangle,

Base = 55 feet

Height = 48 feet

Length of the rope = ?

By Pythagoras theorem:

Square of longest side = Square of base + Square of height

               (Longest\  side)^{2} =  55^{2} +48^{2}

                (Longest\  side)^{2} =  3025+2304

               (Longest\  side)^{2} =  5329

                 Taking root both side

            \sqrt[2]{(Longest\ side)^{2} } =\sqrt[2]{5329}

                Longest\  side =  73

Thus, length of the rope is 73 feet.
